The technical solutions of the present invention will be clearly and completely described in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiment is only the present invention. Some embodiments, not all of the embodiments, are set forth. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the invention.

In accordance with an embodiment of the present invention, a method of determining a location of a terminal is provided.

Referring to FIG. 1, FIG. 1 is a flowchart of a method of determining a location of a terminal according to an embodiment of the present invention.

At step S110, a wireless signal transmitting device MAC address when the terminal connects to the Internet is acquired.

The terminal connects to the Internet by receiving a wireless network signal transmitted by the wireless signal transmitting device, and the wireless signal transmitting device can convert the wired network signal into a wireless network signal to provide a device of a device within the coverage of the signal, and the device within the signal coverage of the wireless signal transmitting device can connect to the Internet by wirelessly receiving the wireless network signal, for example, a wireless router, and the wired network can be The road signal is converted into a wifi signal (wireless fidelity signal), and nearby wireless network devices (eg, wifi-enabled notebooks, mobile phones, tablets, etc.) can access the Internet by receiving their transmitted wifi signals. . It should be understood that the wireless signal transmitting apparatus of the present invention is not limited thereto, but may be any suitable device capable of transmitting a wireless signal.

When the terminal accesses the Internet through a wireless network signal provided by the wireless signal transmitting device, the MAC address of the wireless signal transmitting device (ie, the physical address or the hardware address is globally unique) Sex) can be obtained.

At step S120, it is determined whether the MAC address exists in the correspondence database of the pre-configured MAC address and location. The correspondence between the MAC address and the latitude and longitude can be saved in the correspondence library between the MAC address and the location. Wherein, the position can be represented by latitude and longitude, that is, the correspondence between the MAC address and the latitude and longitude is stored in the correspondence database of the MAC address and the location.

Reference may be made to FIG. 2, which is a flow diagram of a pre-configured library of correspondences between MAC addresses and locations, in accordance with one embodiment of the present invention. As shown in FIG. 2, the correspondence library of MAC addresses and locations is pre-configured by the following steps.

At step S210, a MAC address and location information corresponding to each MAC address are collected. The MAC address is a MAC address of a wireless signal transmitting device, such as a wireless router. The location information may include: a latitude and longitude of a location where the wireless network signal (eg, wifi signal) transmitted by the wireless signal transmitting device corresponding to the MAC address is connected to the Internet.

Specifically, when any mobile terminal (such as, but not limited to, a smart phone, a tablet, etc.) is connected to the Internet by a wireless network signal transmitted by any wireless signal transmitting device, such as but not limited to a wifi signal transmitted by a wireless router. And obtaining a MAC address of the wireless signal transmitting device that transmits the wireless network signal, and if the terminal has a GPS positioning function, acquiring a position (latitude and longitude) when the terminal accesses the Internet through the wireless signal transmitting device ) information can be installed at the end of the mobile The APP (the client application) collects a large amount of log information to obtain the MAC address of the wireless signal transmitting device and its corresponding location information. Alternatively, wireless signal transmitting device information and location information of wireless network signals transmitted throughout the city can be received and recorded by installing a wireless signal receiver (eg, a wifi receiver) on a public transportation vehicle.

According to an embodiment of the present invention, the MAC address and its location information appearing within a predetermined acquisition time before the current time may be collected, for example, the terminal accessing the Internet accessing the Internet within the last 30 days (30 days before the current time) The wireless signal transmitting device MAC address at the time of the network and the location information when the terminal accesses the wireless network signal provided by the wireless signal transmitting device, wherein the terminal has a positioning function.

Since the wireless network signals transmitted by the wireless signal transmitting device have a certain effective coverage (for example, but not limited to, generally within 50 meters), each wireless signal transmitting device is collected by different terminals having a positioning function. One or more latitude and longitude information (different terminals use different wireless network signals transmitted by the device to access the Internet at different locations within the effective coverage of the device signal; or, the same terminal may be at different times, at the wireless signal transmitting device The different locations within the effective coverage of the signal are connected to the wireless network signal transmitted by the wireless signal transmitting device, that is, the location information corresponding to each MAC address includes one or more latitude and longitude information, wherein each latitude and longitude information The latitude and longitude of the location where the wireless terminal signals of the different terminals are connected to the Internet through the wireless network signal provided by the wireless signal transmitting device or the latitude and longitude of the location where the same terminal is connected to the wireless network signal provided by the wireless signal transmitting device at different times.

At step S220, the latitude and longitude corresponding to each MAC address is determined according to each of the collected MAC addresses and their corresponding location information, to obtain a correspondence library of MAC addresses and locations.

In order to explain this step more clearly, an alternative embodiment of this step is described with reference to FIG. FIG. 3 is a flowchart of determining a latitude and longitude corresponding to each MAC address according to each collected MAC address and its corresponding location information to obtain a correspondence between a MAC address and a location according to an embodiment of the present invention. .

As shown in FIG. 3, determining the latitude and longitude corresponding to each MAC address according to each collected MAC address and its corresponding location information may include steps S310-S320.

At step S310, the collected location information corresponding to each MAC address is processed to obtain one or more MAC address latitude and longitude data corresponding to each MAC address.

The latitude and longitude data of each MAC address may include: a MAC address and a set of latitude and longitude (longitude and latitude) corresponding to the MAC address, where the latitude and longitude is a wireless corresponding to a device by the MAC address The latitude and longitude of the location where the wireless network signal transmitted by the signal transmitting device is connected to the Internet. As described above, the location information corresponding to each MAC address includes one or more latitude and longitude information, wherein each latitude and longitude information is a location where different terminals access the Internet through the wireless network signal provided by the wireless signal transmitting device. The latitude and longitude of the location of the latitude and longitude or the location of the same terminal at different times by the wireless network signal provided by the wireless signal transmitting device. Therefore, the location information of each MAC address is made For example, one or more MAC address latitude and longitude data corresponding to each MAC address can be obtained. For example, processing any latitude and longitude information in the location information of a certain MAC address to obtain a MAC address latitude and longitude data corresponding to the MAC address, and the format of the data may be [mac, lat, log], wherein, mac Indicates the MAC address, lat represents latitude, and log represents longitude.

According to an embodiment of the present invention, each MAC address latitude and longitude data may further include: a number of days when the MAC address appears latitude and longitude data and a signal strength at the time of occurrence. The data format can be [mac, lat, log, signal, log_days], signal indicates signal strength, and log_days indicates the number of days. Wherein, a MAC address latitude and longitude data appears in the day (any day of the scheduled collection time before the current time), and the data appears as one day, and no matter how many times the data appears on the day, the data is recorded as One day, for example, collecting 30 days of data, a MAC address latitude and longitude data appears 5 times on the 3rd day, 1 time on the 5th day, 3 times on the sixth day, then the number of days of the IP address latitude and longitude data appears It is 3 days.

According to an embodiment of the present invention, the number of days in which the latitude and longitude data of one or more MAC addresses corresponding to each MAC address appears may be summarized, and one or more MAC addresses latitude and longitude corresponding to each MAC address are filtered out. The MAC address latitude and longitude data of the number of days in the data is less than the predetermined number of days. For example, if an latitude and longitude data of an IP address appears only for one day, and the data is likely to be abnormal data, the data is removed.

At step S320, one or more corresponding to each MAC address The MAC address latitude and longitude data determines the latitude and longitude corresponding to each MAC address.

In order to explain this step more clearly, an alternative embodiment of this step is described with reference to FIG. 4 is a flow chart showing the steps of determining the latitude and longitude corresponding to each MAC address according to one or more MAC address latitude and longitude data corresponding to each MAC address according to an embodiment of the present invention.

As shown in FIG. 4, at step S410, it is determined whether the distance between the locations corresponding to the latitude and longitude data of each of the two MAC addresses in the one or more MAC address latitude and longitude data corresponding to each MAC address exceeds the first predetermined distance. .

That is, by judging whether the distance between the positions corresponding to the latitude and longitude data of each of the two MAC addresses in the one or more MAC address latitude and longitude data corresponding to each MAC address exceeds the first predetermined distance, Whether the location of the latitude and longitude data of one or more MAC addresses corresponding to the MAC address is dense, that is, whether the location where the MAC address appears is dense. The first predetermined distance may be set according to a specific situation. For example, a wireless network signal transmitting device with a wireless network signal coverage of about 50 meters is relatively common (for example, a wireless router), and the first predetermined The distance is set to 100 meters.

At step S420, if the distance between the locations of the latitude and longitude data of each of the two MAC addresses in the one or more MAC address latitude and longitude data does not exceed the first predetermined distance, the one or more MACs are The average of the latitude and longitude of the address latitude and longitude data is determined as the MAC address Corresponding latitude and longitude.

If the distance between the locations corresponding to the latitude and longitude data of each of the two MAC addresses in the one or more MAC address latitude and longitude data corresponding to the MAC address does not exceed the first predetermined distance, one corresponding to the MAC address may be determined. Or the location of the occurrence of the latitude and longitude data of the plurality of MAC addresses is relatively dense, and the latitude and longitude in the latitude and longitude data of the one or more MAC addresses may be averaged (ie, the longitude in the latitude and longitude data of the one or more MAC addresses) And latitude are respectively averaged), and the obtained average latitude and longitude is taken as the latitude and longitude corresponding to the MAC address. If the distance between the positions corresponding to the latitude and longitude data of any two MAC addresses in the one or more MAC address latitude and longitude data corresponding to the MAC address exceeds the first predetermined distance, the process may proceed to step S430.

At step S430, the latitude and longitude corresponding to the MAC address is determined according to the predetermined number of MAC address latitude and longitude data in which the number of days in the latitude and longitude data of the one or more MAC addresses is the highest.

Specifically, if the distance between the locations of the latitude and longitude data of any two of the one or more MAC address latitude and longitude data exceeds the first predetermined distance, one or more corresponding to the MAC address may be determined. If the location of the MAC address latitude and longitude data is sparse, the latitude and longitude corresponding to the MAC address may be determined according to the predetermined number of MAC address latitude and longitude data of the one or more MAC address latitude and longitude data.

For example, the latitude and longitude of the three MAC addresses with the highest number of days in the latitude and longitude data may be according to one or more IP addresses corresponding to the MAC address. The data determines the latitude and longitude corresponding to the MAC address. The one or more MAC address latitude and longitude data corresponding to the MAC address may be sorted by the number of days of occurrence to extract the MAC address latitude and longitude data of the three most frequently occurring days. And determining the latitude and longitude corresponding to the MAC address according to the number of days of occurrence of the latitude and longitude data of the three MAC addresses with the highest number of days and the distance between the corresponding locations.

Specifically, the distance between the MAC address latitude and longitude data of the number of days in which the extracted MAC addresses of the three most frequently occurring latitude and longitude data are corresponding to the positions of the other two MAC address latitude and longitude data may be respectively determined, and the number of days of occurrence may be the most The distance between the locations corresponding to the latitude and longitude data of the MAC address does not exceed the MAC address latitude and longitude data of the third predetermined distance, and the longitude data and the latitude data in the latitude and longitude data of the MAC address with the most occurrence of the number of days are respectively weighted by the number of days of occurrence. Perform weighted averaging, and obtain the obtained longitude average and latitude average as the latitude and longitude corresponding to the MAC address. For example, the latitude and longitude data of the three most frequently occurring MAC addresses extracted by a certain MAC address are r1 (the maximum number of days), r2, r3, where r1=[mac,lat1,log1], r2=[mac,lat2, Log2], r3=[mac, lat3, log3], the third predetermined distance may be the same as the first predetermined distance, for example, may be set to 100 meters, respectively calculating the corresponding position of r1 and the other two MAC address latitude and longitude data The distance between the corresponding positions of r1 and r2 is within 100 meters, and the distance between the corresponding positions of r1 and r3 is also less than 100 meters, then the longitude in r1, r2, r3 The data and latitude data are weighted and averaged by the number of days in which r1, r2, and r3 appear, respectively. The longitude average and the latitude average are the latitude and longitude corresponding to the MAC address; or, if the distance between the corresponding positions of r1 and r2 is within 100 meters, and the distance between the positions corresponding to r1 and r3 If it is greater than 100 meters, the longitude and latitude data of r1 and r2 are weighted and averaged by the number of days of occurrence of r1 and r2, and the average longitude and latitude are obtained as the latitude and longitude corresponding to the MAC address. Or, if the distance between r1 and r2, r1 and r3 is greater than 100 meters, the latitude and longitude of r1 with the largest number of days will appear as the latitude and longitude corresponding to the MAC address.

According to an embodiment of the present invention, after determining the latitude and longitude corresponding to each of the acquired MAC addresses, the method further includes the step of determining the reliability of the location corresponding to each MAC address.

Specifically, the reliability of the location corresponding to each MAC address may be determined according to the signal strength corresponding to the latitude and longitude data of one or more MAC addresses corresponding to the MAC address. For each MAC address, the reliability of each MAC address latitude and longitude data may be determined according to the signal strength corresponding to each MAC address latitude and longitude data corresponding to the MAC address, for example, the signal strength is -50dbm<I _signal <0dbm The MAC address latitude and longitude data, the credibility can be set to 1 (the credibility is relatively strong), the signal strength -70 <I _signal <-50dbm MAC address latitude and longitude data, the credibility can be set to 2, the signal strength - 90dbm<I _signal <-70dbm MAC address latitude and longitude data, the credibility can be set to 3, etc., not enumerated here, and then the MAC address corresponding to one or more MAC addresses through latitude and longitude data The credibility that occurs most frequently in the credibility is determined as the credibility of the location corresponding to the MAC address.

According to the embodiment of the present invention, when the pre-configured correspondence between the MAC address and the location is used, if the found terminal is connected to the Internet, the location corresponding to the MAC address of the wireless signal transmitting device is more reliable. If the value is low, the corresponding location of the MAC address and the location may be combined to determine the location corresponding to the MAC address.

The above is the step of pre-configuring the correspondence library of the MAC address and the location. Next, return to step S130 in Fig. 1.

At step S130, if the MAC address exists in the correspondence database of the pre-configured MAC address and the location, the location corresponding to the MAC address in the corresponding relational library is determined as the current location of the terminal. . That is, if the MAC address of the wireless signal transmitting device connected to the Internet by the terminal exists in the pre-configured correspondence between the MAC address and the location, the search is performed from the correspondence database of the pre-configured MAC address and location. The location corresponding to the MAC address, that is, the latitude and longitude corresponding to the MAC address, determines the latitude and longitude corresponding to the MAC address as the latitude and longitude of the current location of the terminal.

If the MAC address does not exist in the correspondence between the MAC address and the location, proceed to step S140 to obtain an IP address of the terminal. That is to say, if the MAC address does not exist in the correspondence database of the MAC address and the location, the location of the terminal may be determined according to the IP address of the terminal.

At step S150, it is determined whether the IP address exists in the correspondence database of the pre-configured IP address and the location, the IP address and the location The corresponding relationship library stores the correspondence between the IP address and the location, wherein the location is represented by latitude and longitude, that is, the correspondence between the IP address and the latitude and longitude is stored in the correspondence database between the IP address and the location.

Reference may be made to FIG. 5, which is a flow diagram of a library of pre-configured correspondences between IP addresses and locations, in accordance with one embodiment of the present invention.

As shown in FIG. 5, the correspondence library of IP addresses and locations is pre-configured by the following steps.

At step S510, an IP address and location information of each IP address are acquired. The location information of the IP address includes: latitude and longitude information of a location where the IP address is accessed by the IP address, that is, a latitude and longitude of a location where the terminal is located when the terminal accesses the IP address by using the IP address.

Specifically, considering the timeliness of the data, the IP address of the Internet and the location information of each IP address can be collected within a predetermined collection time before the current time. For example, the IP address of the Internet in the last 30 days can be collected and each Location information of IP addresses. Since the IP address is dynamically allocated, the IP address may have different locations (latitude and longitude) when surfing the Internet at different times. Therefore, one or more latitude and longitude information may be collected for each IP address, that is, each IP address. The location information of the address includes one or more latitude and longitude information, wherein each latitude and longitude information is a latitude and longitude of a location where the terminal is located when the Internet is accessed by the IP address at any time and at different terminals.

At step S520, the latitude and longitude corresponding to each IP address is determined according to the collected location information of each IP address.

To explain this step more clearly, an alternative embodiment of this step is described with reference to FIG. Figure 6 is a diagram of an embodiment of the invention A flowchart of determining the latitude and longitude of each IP address (step S520) is determined according to the collected location information of each IP address.

In step S610, the collected IP address and the location information of each IP address are processed to obtain one or more IP address latitude and longitude data corresponding to each collected IP address.

According to an embodiment of the present invention, the collected latitude and longitude information included in the location information of each IP address may be processed to obtain IP address latitude and longitude data corresponding to each IP address, because each IP address is The location information includes one or more latitude and longitude information, so that the location information of each IP address is processed to obtain one or more IP address latitude and longitude data corresponding to the IP address, wherein each IP bit The address latitude and longitude data includes: the IP address and a set of longitude and latitude data of the IP address. For example, processing any latitude and longitude information in the location information of an IP address to obtain an IP address latitude and longitude data corresponding to the IP address, and the format of the data may be [ip, lat, log], where ip Indicates the IP address, lat indicates the latitude, and log indicates the longitude. In order to achieve a certain precision, the longitude data and the latitude data can be processed according to predetermined rules. For example, the longitude data and the latitude data can be reserved for 3 digits after the decimal point. The digits are digitized (intercepted to 3 digits after the decimal point) to ensure a reasonable error of the actual geographical position corresponding to each group of latitude and longitude data (the error of 0.01 degree latitude and longitude is within 1 km).

According to an embodiment of the present invention, the method further includes: removing the processed IP address from the latitude and longitude data by the IP address appearing in the latitude and longitude data less than the predetermined number of days. For example, the latitude and longitude data of an IP address is only One day, this information is likely to be abnormal data, then the data is removed.

At step S620, the latitude and longitude corresponding to each IP address is determined according to one or more IP address latitude and longitude data corresponding to each IP address.

Referring to FIG. 7, FIG. 7 is a flowchart of a step (step S620) of determining latitude and longitude corresponding to each IP address according to one or more IP address latitude and longitude data corresponding to each IP address according to an embodiment of the present invention.

At step S710, for each IP address, the weight of each IP address latitude and longitude data corresponding to the IP address is determined. That is to say, for each IP address collected, the weight of each IP address latitude and longitude data corresponding to one or more IP address latitude and longitude data is determined.

Specifically, reference may be made to FIG. 8. FIG. 8 is a flowchart of a step (step S710) of determining a weight of each IP address latitude and longitude data corresponding to the IP address for each IP address according to an embodiment of the present invention. Figure.

At step S810, one or more IP address latitude and longitude data appearing within a predetermined range of locations corresponding to each IP address latitude and longitude data corresponding to the IP address are obtained.

For example, all IP address latitude and longitude data may be obtained within a range of 2 km from the position corresponding to the latitude and longitude in each IP address latitude and longitude data corresponding to the IP address.

At step S820, the number of days in which the latitude and longitude data corresponding to each IP address corresponding to the IP address appears within a predetermined time range and the number of days in which the latitude and longitude data of one or more IP addresses appear within a predetermined range of the corresponding location occurs Determining latitude and longitude data of each IP address corresponding to the IP address the weight of.

Specifically, the IP addresses of each IP address appearing within a predetermined range of locations corresponding to the latitude and longitude data may be summed by the number of days in which the latitude and longitude data of each IP address in the latitude and longitude data appears, to obtain the IP. The total number of days corresponding to the latitude and longitude data of the address, and counts the number of days in which the latitude and longitude data of the IP address appears, and then weights the total number of days and the number of days corresponding to each latitude and longitude data of each IP address by a predetermined weight to obtain each IP address. The weight of the latitude and longitude data.

According to an embodiment of the present invention, the number of days in which the latitude and longitude data of one or more IP addresses corresponding to each IP address is collected may be counted, and the number of days in which all latitude and longitude data of the IP address appear is obtained, wherein one IP address is latitude and longitude. The data appears in the day (any day of the scheduled collection time before the current time) as one day of the data, and no matter how many times the data appears on this day, it is recorded as one day of the data.

For example, the number of days in which all IP address latitude and longitude data (including the IP address latitude and longitude data itself) within 2 km of each IP address latitude and longitude data can be obtained, and summed to obtain the total number of days corresponding to the latitude and longitude data of the IP address. And obtaining the number of days of the IP address latitude and longitude data appearing within a predetermined time range (for example, 7 days before the current time), and weighting the corresponding total number of days and the number of days of occurrence according to a predetermined weight (for example, the corresponding The total number of days and the number of days that appear are weighted according to a weight ratio of 1:4), and the weighted value is used as the weight of the latitude and longitude data of the IP address.

In the above steps S810 to S820, the IP address corresponding to the IP address is obtained. One or more IP addresses are weighted by latitude and longitude data for each IP address in the latitude and longitude data, and then returned to FIG.

At step S720, the latitude and longitude in the latitude and longitude data of the IP address with the highest weight in the latitude and longitude data of the one or more IP addresses corresponding to the IP address is determined as the latitude and longitude corresponding to the IP address.

Specifically, in step S710, determining the weight of each IP address latitude and longitude data in one or more IP address latitude and longitude data corresponding to the IP address, the latitude and longitude data of the IP address with the largest weight may be determined. The latitude and longitude in the latitude and longitude data of the IP address with the largest weight is determined as the latitude and longitude corresponding to the IP address, that is, the latitude and longitude of the location corresponding to the IP address.

Steps S710 to S720 are performed to obtain the latitude and longitude of the position corresponding to each acquired IP address, and then return to FIG. 5.

At step S530, the determined latitude and longitude corresponding to each IP address is combined with the pre-acquired IP address base library to obtain a correspondence library of IP addresses and locations.

Specifically, the determined latitude and longitude corresponding to each IP address can be compared with the pre-acquired IP address base library, and the IP address and its corresponding latitude and longitude that do not exist in the IP address base database are added to the IP. In the correspondence between the address and the location, for the IP address existing in the IP address base library, it is determined whether the area where the latitude and longitude corresponding to the IP address is located and the latitude and longitude corresponding to the IP address in the IP address base database The areas in which they are located are the same. If they are the same, the IP address and its corresponding latitude and longitude are added to the corresponding relationship library of the IP address and the location. If they are different, the IP address and the IP address are The corresponding latitude and longitude in the IP address base library is added to the correspondence database of the IP address and the location, and finally the determined latitude and longitude corresponding to each IP address and the pre-acquired IP address base library are merged into an IP address and The correspondence library for the location.

For example, the IP address base library may be an operator IP library, and the operator IP library may provide the latitude and longitude corresponding to the IP address and the location of the city. For example, the latitude and longitude corresponding to an IP address determined according to step S520 above is [ Lata,loga], in the operator IP library, the latitude and longitude corresponding to the IP address and the city where it is [latb, logb, cityb], determine whether its latitude and longitude [lata, loga] is in the cityb area (city with latitude and longitude) In the range), if the latitude and longitude is in the area of the cityb, take [lata, loga] as the latitude and longitude corresponding to the IP address, and add it to the correspondence database of the IP address and the latitude and longitude. If not, take [ Latb, logb] is used as the latitude and longitude corresponding to the IP address, and is added to the correspondence library of IP address and latitude and longitude.

According to an embodiment of the present invention, after the correspondence library of the IP address and the location is configured, the correspondence library of the IP address and the location may be updated every predetermined time period. Since the IP is dynamically allocated, the location corresponding to the IP address may change, or an uncollected IP address may appear. Therefore, the correspondence library of the IP address and the location may be updated every predetermined time. The predetermined length of time can be determined on a case-by-case basis. For example, it can be updated every 10 minutes.

Referring to FIG. 9, FIG. 9 is a flowchart of updating a correspondence library of the IP address and location every predetermined time length according to an embodiment of the present invention.

At step S910, the IP address appearing on the day and the location information of each IP address are collected.

At step S920, the latitude and longitude of the location information of each IP address that is closest to the current time is determined as the latitude and longitude corresponding to the IP address. That is, the latest latitude and longitude information of each IP address collected is determined as the current latitude and longitude corresponding to the IP address.

At step S930, it is determined whether the IP address exists in the correspondence database of the IP address and the location. That is, it is determined whether the IP address can be found in the correspondence library in which the IP address is the location.

At step S940, if the IP address does not exist in the correspondence database of the IP address and the location, the correspondence between the IP address and the current corresponding latitude and longitude is added to the IP address. The correspondence with the location in the library. If the IP address exists in the correspondence library of the IP address and the location, proceed to step S950.

At step S950, if the IP address exists in the correspondence database between the IP address and the location, determining the corresponding latitude and longitude of the IP address in the correspondence database of the IP address and the location Whether the distance between the latitude and longitude corresponding to the IP address currently exceeds the second predetermined distance.

If the distance between the corresponding latitude and longitude of the IP address in the correspondence library of the IP address and the location and the current latitude and longitude corresponding to the IP address exceeds the second predetermined distance, proceed to step S960, where The latitude and longitude corresponding to the IP address in the correspondence database of the IP address and the location is replaced by the current latitude and longitude corresponding to the IP address. If the IP address is in the correspondence between the IP address and the location, the corresponding latitude and longitude and the IP address If the distance between the latitude and longitude corresponding to the address does not exceed the second predetermined distance, no processing is required, that is, in the correspondence library of the IP address and the location, the latitude and longitude corresponding to the original IP address is still retained.

The above is the step of pre-configuring the correspondence library of the IP address and the location. Next, return to step S160 in Fig. 1.

If the IP address exists in the correspondence database of the pre-configured IP address and the location, the process may proceed to step S160, where the location corresponding to the IP address is determined as the current location of the terminal. That is to say, if the IP address of the terminal exists in the pre-configured IP address and location correspondence library, the IP address corresponding to the IP address is searched from the pre-configured IP address and location correspondence library. Position (latitude and longitude), the latitude and longitude of the location corresponding to the IP address is determined as the latitude and longitude of the current location of the terminal.

If the IP address does not exist in the pre-configured correspondence between the IP address and the location, the location failure of the terminal may be determined at step S170. That is to say, if the latitude and longitude corresponding to the IP address of the terminal is not found in the correspondence database of the IP address and the location, the positioning of the terminal fails.
